GALESBURG — Police have not yet made any arrests in Sunday night's shooting that resulted in the death of 15-year-old Javon Butler.

Brandon J. Kenney, 18, and Alex R. Horton, 18, are wanted in connection with the shooting. The warrant for Kenney has him facing charges of first-degree murder and aggravated discharge of a firearm with bond set at $1 million. The warrant for Horton indicates he is facing a charge of possession of a firearm by a felon with bond at $250,000.

"We're still actively looking for them, but at this point we haven't been able to find them," Galesburg Police Lt. James Bradford said Thursday. "We're getting a multitude of tips, we're checking multiple locations."

Kenney has a number of prior arrests, many being petty offenses as a minor, as well as two criminal felonies filed this year as an adult, according to records at the Knox County Courthouse. Kenney was arrested in connection with a stolen vehicle in January and again for residential burglary and theft in May, all felony charges. The burglary and theft cases are ongoing.

Horton also has prior petty offense arrests as a minor, as well as a January misdemeanor arrest for criminal damage to property and a felony arrest for burglary as an adult. No record of a felony conviction has been located at this time, though Bradford assured Horton has a prior felony conviction on his record.

"Sometimes there is a lag from when the system updates, but he had a prior conviction. On something like this, we wouldn't make a mistake like that," Bradford said.

The inclusion of prior felony upgraded the arrest warrant for Horton to possession of a firearm by a felon.

"He has a prior felony, or the judge wouldn't have signed off on it," Bradford said.

The incident that left Butler dead happened about 8:50 p.m. Sunday. Police responded to the call and found Butler in the backyard at 607 Monmouth Blvd. He was pronounced dead at the scene by Knox County Coroner Mark Thomas. No other details of the shooting have been released and the investigation into the shooting is ongoing.
